Absolutely true. I've gone the corporate route (almost 20 years). I did the entrepreneur thing with a funded startup (which eventually failed đ).
Solopreneurship finally gave me the freedom and flexibility I always wanted. Now, I own my calendar. I get to work out every morning, spend more time with my family, and work with people of my choosing.
Yes, it can get lonely. That's why I've created my own communities and joined a few. It helps! Plus, my business is all about coaching, so I get to talk with clients every day.
Solopreneurship is the best way to ease into semi-retirement, too. I enjoy working when I'm building my own business instead of grinding away in someone else's.
